Not always is it neccessary to lug your super-tele-zoom around to make interesting shoots of "wildlife". Especially when the wildlife is not so shy as to run/fly away immediately.
See this photo which was taken with a fisheye (!).
"War of the Sparrows"

I held the camera freely as close as I could get without chasing the sparrows away. Did not look through the viewfinder, as the close proximity of my body/head would have surely irritated them. Let the cam take care of the rest. And naturely shot a series to get at least one good picture. You can see the shadow of the cam+lens on the table...

So don't wait for your next tele lens - just go happily shooting what creeps and flutters around you

Yep, they're the reason I left New Zealand hungry I often noticed waiters giving some of the meal's rests to the birds. Something you'd surely never see in Germany where sparrows are considered a plague...
